Book excerpt: This is a review of new results on the tau lepton. The results include precise measurements of the lifetime, measurements of the decay tau− .-->. .pi.−2.pi.°nu/sub tau/ with much improved precision, and limits on decay modes containing eta mesons, including the second-class-current decay tau− .-->. .pi.−eta nu/sub tau/. The implications of these new results on the discrepancy in the one-charged-particle decay modes are discussed. 52 refs., 6 figs., 2 tabs.
